SHADE-HOLDER.

Specification of Letters Patent.

Patented May 26, 19 14.-

Application filed October 23, 1913. Serial No. 796,787.

To all whom it may concern Be it known that I, MORRIS A. FRIEDMAN, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented a certain new and useful Improvement in Shade- IIolders, of which the following is a specification.

The invention relates to improvement in shade holders, and has for its object to produce a device in which the shade holder can be adjusted and swung in position so as to permit of the proper ventilation of the room.

IVith the present method of holding the shade securely in place at the top of the window, it is impossible to secure the proper ventilation because if the window is open from the top, the shade extended and the window also raised from the bottom, it is impossible to secure the proper circulation of the air for the reason that the air entering at the bottom will rise between the shade and window and escape at the top. This prevents the escape of foul air from the room. With my device this is eliminated. The fresh supply of air is admitted through the lower opening of the window, and the foul air of the room is allowed to pass out through the upper opening of the window when my improved device is properly adjusted. This and further objects will more fully appear from an examination of the specification and accompanying drawings, considered together or separately.

My invention is illustrated in the accompanying drawings in which the same parts are designated by similar reference characters in all the drawings. 7

Figure 1 is an interior view of the window equipped with my improved shade roller support. Fig. 2 is a sectional View taken on the line 22 of Fig. 1 showing the window lowered from the top and raised from the bottom, and with a roller adjusted to its extreme lower position. Fig. 3 is a detail elevation of the support partly in section and with parts broken away. Fig. 4 is a sectional view on the line et-4t of Fig. 3. Fig. 5 is an interior view of the window similar to Fig. 1, but showing a modification of my improved shade roller support. Fig. 6 is a detail view of one of the rollers shown in the modification illustrated in Fig,

5. Fig. 7 is a detail view of a roller lock.

In the improvement illustrated in the drawings the apparatus comprises av window frame 1 provided with an upper sash 2 and a lower sash 3. frame 1 are casings 77 in which are pivoted arms 6-6 which carry the shade roller 5, and upon which shade roller there is a shade 4. The casings 77 are provided with lugs 8 by which the casings are secured to the window frame 1. The casings 7-7 are provided with a covering 9, said cover being held in place by screws 10. Within each casing is a pivot 11 which carries a notched disk 12, the notches of which are each engaged by a dog 13 held in position by a spring 14. The shade roller 5 is secured in the arms 66 at one end by the cylindrical trunnion 15 and at the other end by the spear 16. The spear 16 is held securely in place by a shackle 17 which is provided with a pivot 18 to make it properly adjustable and a pin 19 to securely hold'the spear 16 in place. Attached to the arms .66 is a bail 20 upon which there is secured or fastened in any suitable manner a cord 21. This cord passes over a pulley 22 fastened to the top of the window frame 1.-

In Figs. 3 and 4 I have shown the disks 12 as having two notches diametrically arranged, and a dog engaging each notch. With this construction the arms can only be locked in one of two positions, namely: one 180 from the other.

In the modification shown in Figs. 5 and 6 the bail 20 is dispensed with and each arm 6 is provided with an endless cord 21 which passes over a pulley 22 at each side of the frame. In the modification I show only a single dog engaging the disk 12 and the said disk is provided with several notches so that the sha e roller may be locked in any one of several positions.

The operation of the device is as follows: The casings 77 are permanently fastened in the window frame 1 by screws passing through the lugs 8. A shade roller is then secured in the arms 66 of the casings 7-7, and the endless cord is extended around the pulley 22, and secured to the bail 20.

The shade may be raised or lowered in the usual manner. When it is desired to ventilate the room, the cord 21 is pulled down and the arms 6-6 will swing on their pivots, the pull on the cord being suflicient to raise the dogs out of their notches. When the Secured to the window arms reach a position opposite to that they normally occupy each dog will engage the opposite notch and hold the arms in their lowered positions. The top of the shade will now be some distance below the top of the window and the window may now be lowered to the same extent without the danger of the shade being blown out through the opening. The lower sash may be raised thus insuring perfect ventilation. iVhen it is desired to restore the shade to its normal position, the cord will be pulled in the other direction. This will disengage the dogs and swing the arms 66 upward where they will be locked by the engagement of the dogs with the notches.

In accordance with the provisions of the patent statute, I have described the prin ciple of my invention, together with the ap paratus which I now consider to represent the best embodiment thereof, but I desire to have it understood that the apparatus shown is merely illustrative, and that the invention can be carried out in other ways.

Having now described my invention what I claim as new and desire to secure by Letters Patent is:

1. The combination with a window and a shade, of an arm pivoted at each side of the window, said arms carrying a shade, a connection between the arms, a pivot attached to each side of the window provided with a notched disk having dogs in spring pressed ngagement with such disk for securely looking the arms in position, a cord attached to .gagement with each disk,

the connection, and a pulley over which the cord passes.

2. The combination with a window and a shade, of an arm pivoted at each side of the window, said arms carrying a shade, a pivot attached to each side of the window pro vided with a notched disk having dogs in spring pressed engagement with such disks for securely locating the arms in position, a cord attached to each arm, and a pulley over which each cord passes.

3. The combination with a window and a shade, a casing secured to each side of the window, a pivot in each casing, an arm carried by each pivot, a notched disk carried by each pivot, dogs in spring pressed ena hail connecting the arms, cord secured to the bail, and a pulley secured to the window, said cord passing over the pulley.

4. The combination with a window and a shade, of a casing secured to each side of the window, a pivot in each casing, an arm carried by each pivot, a notched disk carried by each pivot, dogs in spring pressed engagement with each pivot, a cord attached to each arm, and a pulley secured in the window, said cord passing over the pulley.

This specification signed and witnessed this 21st day of October, 1913.
